So you know that the formula to find the volume of a cone is V=pi x r^2 x h/3
We know that pi is 3.14 so you plug that number in for the pi symbol. Then we know that r is the radius. Since the diameter is shown in the word problem divide 14.8/2 because the radius is half of the diameter. You should get 7.4 as your radius. Then we already know the height for h/3 which is 8.1. Now that you have all of the information given substitute the formula and you should get:
V=3.14(7.4)^2(8.1/3)
Multiply 3.14 times 7.4 to the second power in which you will get 171.3498
Then, divide 8.1 by 3 and then you should get 2.7.
Multiply 171 by 2.7 (btw I rounded 171.3498 to the nearest tenth) and your final answer should be about 464.
Hope this helps
And if I’m wrong please correct me.
Answer:
(4,0)
Step-by-step explanation:
Plug them into see:
Check (4,0)
In order for the lines to intersect at (4,0) it must be on both lines.
2(4)+0=8 is true because it is saying 8=8
4+0=4 is true because 4=4
So (4,0) is a intersection point.
Check (0,4)
2(0)+4=8 is not true because it is saying 4=8
0+4=4 is true so it's on this line while not on the other line.
So (0,4) is not an interestion point for the mentioned lines.
Well all points can't be on the line since (0,4) is not on both lines but just one of them.
We could have solve this out instead plugging in but the problem gave us the option here with the choices.
Answer:
Domain is all real numbers.
Step-by-step explanation:
Given:
The function is given as:
A function is like a machine which gives an output for a given output.
The input to a function is called its domain. The domain is the set of all possible values for which the function is defined. The domain is represented by the independent variable 'x'.
The output of the function is the function value for the given 'x'. It is represented by 'y' or 'f(x)'.
So, the domain must include only those values which give a definite value for .
Here, the given function is a cubic function. A cubic function is one which has the highest power of 'x' as 3. A cubic function is defined for all real values of 'x'.
Therefore, the domain of the given function is all real values.
Answer:
If it was supposed to be 6.4 x 10^⁷ then answer 4 is correct.
